Event that indicates a suite (or other entity) has completed running a test that failed.

For example, trait Suite uses TestFailed to report
that a test method of a Suite completed abruptly with an Exception.

To create instances of this class you may
use one of the factory methods provided in its companion object. For example, given a
report function named report, you could fire a TestFailed event like this:

The suite class name parameter is optional, because suites in ScalaTest are an abstraction that
need not necessarily correspond to one class. Nevertheless, it most cases each suite will correspond
to a class, and when it does, the fully qualified name of that class should be reported by passing a
Some for suiteClassName. One use for this bit of information is JUnit integration,
because the "name" provided to a JUnit org.junit.runner.Description appears to usually include
a fully qualified class name by convention.
